The Lowdown
Alright, Rusty here again, switching to feet. Let's look at the run at Jaconé.
We have a solid window of surf coming up, but it's not for the faint of heart. The water's a touch warmer than usual for this time of year at 74°, so you might get away with a spring suit.
The main event kicks off Wednesday the 12th with a strong, pulsing S swell. We're talking a solid 8 ft face, with a long 12-second period pushing a heap of energy (1523 energy score). The morning session will be the best of the day with a light cross-off breeze keeping things clean. But, if you're a beginner, 8 ft is serious. This is for experienced surfers only.
Thursday the 13th is a real standout. The wind goes glassy in the morning, making it dead clean. The swell holds at a solid 7 ft from the S, and the consistency is excellent. The afternoon actually looks a touch bigger at 8 ft with a longer 14-second period, which really draws out the power.
We see another top morning on Saturday the 15th. Clean 8 ft S swell with a gentle offshore breeze. That's going to be quality. Things start to drop off a bit from Sunday the 16th. The swell backs down significantly and the wind gets patchy, so we'll see a few days of smaller, less exciting surf through to mid-week.
There's a bit of a lull after that, but hang in there. The outlook gets interesting again on Sunday the 23rd. The afternoon session serves up a clean 6 ft SSW swell with a light cross-off breeze. It's worth a paddle.
But the real standout for the second week is Monday the 24th. This one's a proper gem. It's got a solid 8 ft S swell with a clean, gentle offshore wind from the NE all morning. That's as good as it gets on paper. Keep a note of this date – it's a promise.
The final highlight I see is the morning of the 27th. It's a late call, but the forecast has 8 ft S swell with glassy conditions. If you can wait, it's a beautiful way to finish the run.
Remember, with the S swell direction being the best for Jaconé, these swells are going to wrap in with real purpose. The crowds are sometimes a factor here, so get out there before the sun's up.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
